Firstly you should ignore the 1st review about this place...the one which goes on about a hotel, this is clearly not refering to Casa in Trastevere!
This place is lovely, hidden in the back streets of Trastevere, and only 10 / 15 mins walk to all of the major sights, it is a great place to stay. We have been to Rome many times and have stayed in a number of different apartments located in the centre, none have been as good as this one.
I would say that the location was the best thing, the fact you can sightsee during the day but when you come back to the apartment you are away from the crowds. Obviously you have Trastevere on your door step, this is prob a 5 min walk away so just far enough away to be from the throughfare. Saying that I would say that on some occassions there was a little bit of noise but compared to staying in town it was nothing.
The apartment was clean, fresh, and we had 2 bathrooms which was great as there was 4 of us sharing the place. The bedrooms were spacious and clean.
I would also comment that apartment didn't have any air conditioning which made for it being very warm at night. We did have a particulary hot week, every day being 30 -35 degrees so hot in fact we had to buy a fan! Air conditioning would just make this place perfect!
I would defnitely recommend this place to stay in Rome.
